Question

希望不要重复。

我在第一个表（用户）中有两个表，列（uid和tokenn）是注册用户的ID。当来自外部网站的访客向(uid)发送消息时，函数将消息发布到(posts table) strong> 和列 (uid) 在帖子表中变为 (to_id)。

我想获取(to_id)的(token)，即users表中的(uid) strong> 以便让 Firebase 将通知推送到该令牌。

用户表：

<头>

id	uid	姓名	电子邮件	密码	令牌
5	6	o	o	o	12313

帖子表：

<头>

id	pid	from_id	to_id	反馈
5			6	12313

我的postsController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\post;
use Auth;
use Lang;

class postsController extends Controller
{
    public function send_feedback(Request $request){
        $this->validate($request,[
            'feedback_image' => 'nullable|image|mimes:jpeg,png,jpg|max:3072',
            'feedback_content' => 'required|max:500'
        ]);
        $pid = rand(9,999999999)+time();
        if (Auth::user()) {
            $from_id = Auth::user()->uid;
        }elseif (Auth::guest()) {
            $from_id = 0;

        $post->to_id = $to_id;
        $post->feedback = $feedback;

 $fcmUrl = 'https://fcm.googleapis.com/fcm/send';
$token = User::where('uid', $to_id)->first()->tokenn;







    $notification = [

        $extraNotificationData = ["message" => $notification,"moredata" =>'dd'];

        $fcmNotification = [

        $headers = [

        //
        
    
        return redirect()->back()->with('feedback_sent',Lang::get('trans.fb_sent'));
    }
    public function postPrivacy(Request $request){
        $pid_var = $request['pid'];
        $pid_ex = explode("_", $pid_var);
        $pid = @$pid_ex[1];
        if ($request['status'] == "true") {
            $updatePrivacy = post::where('pid',$pid)->update(['privacy' => 1]);
        }else{
            $updatePrivacy = post::where('pid',$pid)->update(['privacy' => 0]);
        }
        return $pid;
    }
    public function deletePost(Request $request){
        $checkID = post::where('pid',$request['pid'])->get()->count();
        if ($checkID > 0) {
            $allowed = post::where('pid',$request['pid'])->get();
            foreach ($allowed as $getAllowed) {
                $to_id = $getAllowed->to_id;
                $from_id = $getAllowed->from_id;
            }
            if ($to_id == Auth::user()->uid || $from_id == Auth::user()->uid) {
                $deleteFB = post::where('pid',$request['pid'])->delete();
                return "done";
            }else{
                return Lang::get('trans.delPost_notAllowed');
            }
        }else{
            return Lang::get('trans.err_somethingWrong');
        }
    }
}

我尝试检索消息收件人的令牌，如下所示：

$token=Auth::user()->tokenn; //but it returns the logged in and the sender user's token which is wrong.

$token = User::find($to_id)->tokenn;
$token = User::where('uid', $to_id)->first()->tokenn;

//these both are not working too

当 GUEST 向任何人发送消息时，我需要检索收件人的令牌。

希望我说得很清楚。

您必须在模型目录中创建 User.php

这个类默认在你安装 laravel 的时候创建，但是如果你无意中删除了它，你可以通过以下方式创建它：

php artisan make:model User

并且在您的控制器中，您必须使用此模型而不是 App\Http\Controllers\User。

所以换句话说，你必须使用 App\User 在 Laravel 7 及以下版本中，或在 Laravel 8 中使用 App\Models\User 在您的控制器中，如下所示。

use App\User; // if your laravel version is 7 or below

use App\Models\User; // if your laravel version is 8 or higher

Laravel 从具有相同列的两个表中检索数据
